K = °C + 273.15

Formula

K = °C + 273.15

Kelvin (K) is the absolute temperature scale used in science, physics, and engineering. Unlike Celsius and Fahrenheit, Kelvin has no negative values — it starts at absolute zero (−273.15°C), the coldest temperature theoretically possible. Converting Celsius to Kelvin is essential for thermodynamics, chemistry, and astrophysics calculations.

Add 273.15 to any Celsius value to get Kelvin. Room temperature (20°C) is 293.15 K.
